Photobomber! Rachel Zoe's son Kai expertly upstages his fashionista mom as she poses with Jessica Alba and Molly Sims.

It's the season of giving.
So Rachel Zoe and friends were all about generosity on Sunday during the annual Baby2Baby holiday party at Montage Beverly Hills.
But while the fashionista, 46, turned heads in a chic suit it was her son Kai, four, who stole the show as he photobombed the designer's photo with stars Jessica Alba and Molly Sims.

Rachel looked slick in a velvet jacket with gold buttons and matching trousers with flared legs and a subtle stripe down the side at the event presented by the retailer Toys R Us.
The native New Yorker wore her blonde locks long and loose with a sharp center part while lining her eyes in kohl for drama.
